DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting table for forming a corner of a roof of a temple or the like, and a curved plane used for the corner of a corner.

[0002]

2. Description of the Related Art Conventionally, in order to form a corner warp, a warp condition depends on a worker's long-term intuition, or a line matching the warp is drawn on the side of the material, and a curved plane is formed along the line. I was cutting. 【】

[0006] Corner warping is found especially on the roofs of temples and shrines. When forming corner warping, it is as described above. In the case where Kaneshi is superimposed in two stages, three stages and several stages, it becomes impossible if the degree of warping is not the same, and work cannot be performed by anyone other than an expert.

[0004] Also, even when cutting along a line drawn on the side surface of a material, skill is required to make the cut surface horizontal.

In view of the above, it is an object of the present invention to provide a cutting table capable of easily forming a correct size of a chamfer, and a curved plane used for forming the chamfer. .

[0006]

In order to solve the above-mentioned problems, a corner warp cutting machine according to the present invention has a horizontal portion formed at the center of the upper surface of both side plates connected at a fixed interval. In connection with one side, an upwardly bent part is formed, and one side is connected to the horizontal part, and on the other side, a downwardly bent part having the same shape as the bent part is formed. A material mounting table having an upper surface having the same shape as the bent portion and the bent portion bent downward is provided so as to be slidable in the front-rear direction and up and down.

The curved plane according to the present invention is characterized in that bottom plates are provided on both sides of the cutting blade at the bottom of the main body.

[0008]

The operation of the corner warping cutting table and the curved plane according to the present invention will be described. The material cut into a length substantially equal to the horizontal portion of the upper surface of the side plate and one bent portion connected thereto is cut. The table is placed near the bent portion of the table, which is warped upward, and is fixed by pressing from the side with a fixing tool. The material placing table is composed of a horizontal portion and a bent portion bent downward. Since there is no bent portion bent upward, the material placing table is placed horizontally on the material placing table.

Then, the upper surface of the material is cut by a curved plane along the shapes of the bent portion and the horizontal portion which are warped upward of the side plate. Since the bottom plate is provided on both sides of the cutting blade of the curved plane, when the cutting is performed to a certain thickness, the bottom plate comes into contact with the upper surface of the side plate and the cutting operation can be performed as a guide. Therefore, the upper surface of the material has the same shape as the bent portion and the horizontal portion which are warped upward of the side plate, and the cut surface is formed horizontally without excessive cutting.

Next, the material is once removed from the cutting table, and the material is fixed on the material mounting table by turning the material upside down and moving the bent upwardly bent portion toward the bent downwardly bent side of the material mounting table. For example, the cut material surface matches the shape of the upper surface of the material mounting table. Then, if the material is cut along the shape of the bent portion warped downwardly of the side plate with a curved plane, the front and back surfaces of the bent portion have the same shape. The above is the method of forming the corner warp. The thickness of the corner warp can be adjusted by moving the material mounting table up and down. Further, by moving the material mounting table back and forth, the thickness of the warp of the bent portion can be changed, so that the dimensions as designed can be accommodated.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of the present invention;
FIG. 1 is a longitudinal sectional side view showing an embodiment of a corner warp cutting machine according to the present invention, FIG. 2 is a side view of the same, FIG. 3 is a plan view of the same, FIG.
5 is a bottom view of the same, FIG. 5 is a side view of a roof part of the roof, FIG. 6 is a side view showing one embodiment of the curved plane of the present invention, and FIG. 7 is a bottom view of the same.

In the drawing, reference numeral 1 denotes a pair of left and right long side plates, and a horizontal portion 1A is formed at the center of the upper surface of the side plate 1, and a bent portion which is connected to the horizontal portion 1A and is warped upward to one side. 1B is formed, and a bent portion 1C which is connected to the horizontal portion 1A and has the same shape as the bent portion 1B and is warped downward is formed on the other side. The side plates 1 are connected at regular intervals by connecting bolts 2 and nuts 3 provided before and after the side plates 1 and a connecting rod 4 provided at the bottom.

Reference numeral 5 denotes a material mounting table provided between both side plates 1 and 1, and the upper surface of the material mounting table 5 is formed in the same shape as the horizontal portion 1A and the downwardly bent portion 1C of the side plate 1. . or,
Two screw tubes 6 are buried in the lower surface of the material mounting table 5 at front and rear, and a long hole 8 formed in the screw tube 6 in the front-rear direction of a support plate 7 provided between the both side plates 1 and 1 below the screw tube 6. The threaded rod 9 is screwed. Therefore, the material mounting table can be adjusted up and down by turning the handle 10 of the screw 9. Then, when the material mounting table 5 rises and a gap is formed between the material mounting table 5 and the support plate 7, several kinds of spacers (not shown) having different thicknesses are interposed in the gap.
Further, the material mounting table 5 slides in the front-rear direction because the screw 9 can be slid in the long hole 8 by loosening the screw 9.

Reference numeral 11 denotes a fixture comprising a threaded rod 15 which is screwed into a nut 12 embedded in the side plate 1 from the outside of the one side plate 1 and provided at a tip thereof with a pressing piece 14 for pressing a side portion of a wooden material 13. . Reference numeral 16 denotes a handle of the screw rod 15. The fixing tool 11 is located near both ends of the horizontal portion 1A of the side plate 1 and the bent portions 1B, 1C.
Are provided at approximately four locations at the center.

Reference numeral 17 denotes a curved plane main body, 18 denotes a cutting blade, and 19 denotes a bottom plate attached to the bottom of the curved plane main body 17 and extends on both sides of the cutting blade 18. Reference numeral 20 denotes an arc-shaped bottom plate provided on the front bottom of the curved plane main body 17. The extended portions corresponding to both sides of the cutting blade 18 of the bottom plate 19 abut on the upper surface of the side plate 1 of the cutting table during the cutting operation. In addition, 21 in the figure is a roof portion provided with a corner curvature 22.

[0016]

According to the present invention, the material placed on the material placing table of the cutting table is cut along the upper surface of the side plate, and the bottom plate exists on both sides of the curved plane cutting blade. Since the bottom plate is in contact with the side plate, it does not cut too much, and the cutting surface is horizontal without inclination, so that accurate cutting work can be easily performed by not only skilled workers but also beginners.
In addition, the thickness of the valley and the thickness of the warp at the bent portion can be changed, and this is a useful invention in which the valley can be formed exactly as the dimensions.
